Is Colon Cancer Slow Growing
Why do you read that someone had a clean colonoscopy and then 24 months later they have full blown colon cancer, since it is "slow growing"?
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Varies. ~10yrs: In general, we think about 10 years. Hence the "standard" colon screening recommendation (by colonoscopy) of every 10 years if the colon is well prepped and without pre-cancerous polyps. Colon cancer can grow faster especially in some familial syndromes. Individuals with polyps may and likely do need more frequent followup. Recs individualized by the GI physician. ...Read more
Roughly one year: The immunogenic tumor protein, a post translational modification of MUC5ac is found in most colon Ca. When polyoma enters bowel to form a field effect, one site will develop a Ca. If resected and premalignant normal appearing cells which express MUC 5ac are left behind, suppression is eliminated and one of the foci, staining + for MUC5ac will grow and replace anastomosis in about 1 yr. ...Read more
Yes: Yes. In general, we think most colon cancers take about 10 years to develop. Hence, the guidelines for colonoscopy every 10 years if a "normal" colon is found. However, some familial syndromes result in faster polyp and cancer growth. Also, some individuals may have more or faster growing polyps or cancers. A gastroenterologist should be able to help individualize a surveillance program. ...Read more
I was diagnosed with stage 3 colon cancer, I'm on folfox6. I read cq10 will help in stopping cancer sells from growing. Take it while chemo? Dosage?
Colon cancer I had a colonoscopy 31/2 yrs. Ago but am having trouble lately could polyps grow that quickly I won't have another colonoscopy for 6 mo?
Very unlikely: Adenomatous polyps (the ones that can turn into cancer) become more common the older you are. The more the number of polyps seen and removed, the higher the growth rate and likely the chance of finding new ones. Having polyps or cancer at a young age though should trigger shorter intervals to surveillance colonoscopies. ...Read more
My 63 yr old mom w/ colon cancer, stge 4, is on folfox. Multiple chemo's have failed to shrink or slow down the cancer. Is folfox better/any other?
Avastin (bevacizumab): Folfox or folfiri seem to be the best agents for advance colorectal cancer. In some patients the addition of Avastin (bevacizumab) can be added in some patients. I would expect her oncologist has discussed these options. ...Read more
3 cycles of chemotherapy so far for metastic colon cancer shows therapy working, if 2 cycles are missed due to ill health, will cancer start growing agsin?
No: If 3 cycles of chemo given and well tolerated, evaluation might show stability or regression if drugs working. If missing 2 cycles, this will not allow further regression while off medication, but if resumed a further response may be defined. Most combo drugs for colon cancer may show a termporary response but not cure. The newer combinations with Immunochemotherapy more effective. ...Read more
Are polyps the same as colon cancer? After the doctor takes them out, does a person need chemo or radiation? Can they grow back?
The: The majority of polyps are not cancer. They are benign. Many are completely harmless. Others can grow into bigger polyps, which are called adenomatous polyps. Colonoscopy will remove all polyps. If not removed, these bigger polyps have the potential to develop into cancer. Your doctor would have discussed that with you if cancer were found during your colonoscopy. ...Read more
How fast does colon cancer grow. CT Scans 2 1/2 years apart both negative. Would there have been some change by this point? Pcp says IBS.
First CT scan is not the best way to discover or screen or rule out colon cancer so negative CT scan does not mean anything as far as colon cancer concern colonoscopy is the best way to screen colon cancer
you are kind of young for colon cancer most likely your colon problems are caused by something else like IBS
thank you for using health tap ...Read more
Cancer of the colon: Cancer that forms in the tissues of the colon (the longest part of the large intestine). Most colon cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids). There are estimated 103, 170 (colon); 40, 290 (rectal) new cases and 51, 690 (colon and rectal combined) deaths from colon cancer in us in 2012. Screening with colonoscopy started at age of 50. ...Read more
Cancers: Cancers are abnormal, rapidly growing cells that do not know when to stop growing. These abnormal cells can damage local tissues, can attach to nearby organs or structures, can spread to lymph nodes, or can spread to other organs through the blood stream. Their growth damages what they are attached to, and often cancers encourage new blood flow to themselves. Cancer can grow in the colon. ...Read more
Not always: Colon cancer tends to not have any signs or symptoms when it is early (when it is easiest to treat). That is why screening colonoscopies are so important, to remove any polyps that may become cancer, and to directly look for cancers. Colon cancer can cause bleeding from the rectum, tiredness from anemia, stool changes, or abdominal pain. Other things can cause this too. Best to be seen if? S. ...Read more
Usually not: Early stages of colon cancer often have no symptoms. Colon cancer has long developmental stages starting out as polyps and can take yrs to develop, hence screening colonoscopy is done every 10 yrs for normal folks. Polyps can be removed during colonoscopy. Advanced cancer can cause pain by obstructing bowel, spread to liver, bone, brain, lung etc. See doc regulalry. Good luck. ...Read more
Early detection!: The best thing that improves the chances of curing colon cancer is early detection. So preventive health care and screening are key. All adults should have a colonoscopy at age 50 to look for cancers or early cancers, usually as polyps. If you have a strong family history or certain conditions it is recommended you get earlier screening. Once detected, colon ca usually is cured by surgery, or drugs. ...Read more
Very complicated: Monoclonal theory says that just like we are a living thing, we are born, we have jobs to do and then we die, each cell has a similar cycle of birth, life, and death. Cancer occurs when a cell develops so many mutations that it does not follow that cycle and does not die but can still divide itself and hides from our immune system which is there to detect abnormal cells and destroy them. ...Read more
